DETAILED DESCRIPTION

[0020] In the following, the present application is further described in conjunction with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments without conflict.

[0021] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0022] Embodiment one:

[0023] As shown in Figures 1 to 3 A glass fiber waste powder scrap removal device, characterized in that: it comprises a four-arc surface magnetic iron removal machine 1 for removing iron filings in glass fiber waste powder, a multiple integrated metal separation device 4 for removing metal filings in glass fiber waste powder, an electric heating conveyor 2 and a dehumidifier 3 arranged between the four-arc surface magnetic iron removal machine 1 and the multiple integrated metal separation device 4, the four-arc surface magnetic iron removal machine 1 comprises an absorption box 11, an annular electromagnet 12 arranged at the top of the absorption box 11, an iron filings scraping piece 13 arranged on the absorption box 11 and attached to the annular electromagnet 12, and an iron filings collection box 14 arranged at the bottom of the absorption box 11. The device can efficiently remove iron filings and other metal powder from glass fiber waste, realize integrated production, has high production speed and high production efficiency, can reduce production cost and save energy.

[0024] The annular electromagnet 12 is composed of four arc electromagnets 121. The rotation of the annular electromagnet 12 can continuously magnetically attract the iron filings in the glass fiber waste powder. The annular electromagnet 12 is composed of four arc electromagnets 121, and the power supply of the four arc electromagnets 121 can be controlled independently. When one of the arc electromagnets 121 reaches the inner side of the suction box 11, the power supply is controlled to be cut off to eliminate the magnetic force, thereby releasing the iron filings. The iron filings are scraped by the iron filings scraping piece 13 and then fall into the iron filings collecting box 14. The annular electromagnet 12 continues to rotate, and the arc electromagnet 121 after scraping the iron filings continues to rotate. The magnetic force generated after power supply is turned on continues to attract the iron filings, thereby avoiding the waste of electric energy in the no-material area during the operation of the machine, saving the electric energy for magnetically attracting the iron filings, and continuously removing the iron filings with high efficiency.

[0025] The side of the suction box 11 is provided with a conveying box 15 in communication with the annular electromagnet 12, and the electric heating conveyor 2 and the dehumidifier 3 are arranged on the conveying box 15. The conveying box 15 is used to heat and dehumidify the glass fiber waste powder during conveying, thereby ensuring the normal operation of the subsequent process.

[0026] The outlet of the conveying box 15 is provided with an inclined channel 16 connected with the bottom of the multi-integrated metal separation device 4. The inclined channel 16 is inclined downward and outward by an angle of 5°-45°. The inclined channel 16 is inclined downward and outward by an angle of 5°-45° and has a slope length of 1.5-2 meters, thereby buffering the conveying force and the material falling force and improving the separation efficiency and effect of the metal filings by the subsequent multi-integrated metal separation device 4.

[0027] As shown in Figure 4 , the multi-integrated metal separation device 4 includes a Z-shaped multi-channel 41, a metal filings collecting box 42 arranged at the bottom of the Z-shaped multi-channel 41, and a plurality of feeding fans 43 arranged on the Z-shaped multi-channel 41. The Z-shaped multi-channel 41 is composed of mutually intersecting upward inclined sub-channels 411. The feeding fans 43 are arranged at the tail of the sub-channels 411, and adjacent sub-channels 411 are intersected to form an angle of 90°.

[0028] As shown in Figure 5 , the feeding fans 43 are used to blow and select the glass fiber waste powder. The left and right feeding fans 43 blow and select simultaneously in two directions and in multiple layers. In the direction indicated by the arrow, the glass fiber waste powder with low density is blown upward for feeding, and the metal filings with high density fall downward into the metal filings collecting box 42, thereby effectively removing the metal filings in the glass fiber waste powder and forming the glass fiber powder. The efficiency of wind selection and isolation for removing other metal filings is high, the speed is fast, and the separation effect is good.

[0029] The tail of the sub-channel 411 is provided with a filter screen 44 in communication with a feeding fan 43. Dust leakage is avoided to prevent air pollution. The sub-channel 411 adopts a hollow cuboid structure. Manufacturing is convenient.

[0030] In actual production, the glass fiber waste powder a is fed into the quadruple arc surface magnetic iron removal machine 1 to remove iron filings b contained therein, and the iron filings b fall into the iron filings collection box 14; the glass fiber waste powder a is heated and dehumidified by the electric heating conveyor 2 and the dehumidifier 3, so that the moisture content is less than 0.5%, and the glass fiber waste powder a is fed into the multi-integrated metal separation device 4 through the inclined channel 16; the multi-integrated metal separation device 4 is used to remove metal filings c contained in the glass fiber waste powder a, and the glass fiber waste powder a is blown and selected by the feeding fan 43, the glass fiber waste powder a with low density is blown upward for feeding, forming a glass fiber powder genuine product, and the metal filings c with high density falls downward into the metal filings collection box 42.

[0031] Example two:

[0032] The structure of this example is basically the same as that of example one, except that:

[0033] As shown in Figure 6 , referring to Figure 4 and Figure 5 , the sub-channel 411 adopts a hollow cylindrical structure, and the filter screen 44 is arranged inside. At the same time, chamfers are arranged at the corners, which can avoid the accumulation of glass fiber powder, ensure the smoothness of the entire Z-shaped multi-channel 41, and improve the separation efficiency of metal filings.

[0034] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of protection claimed by the present application.
